การปรับปรุงพันธุ์ต้านทานโรคไวรัสใบหงิกเหลืองของมะเขือเทศ Thai Agricultural
Kanlayanee Chaichana; Prasartporn Smitamana; Maneechat Nikronpun.
Improvement of tomato for resistance to tomato yellow leaf curl virus (TYLCV) were carried out byusing a pedigree and backcrossing methods and crossing between resistant parent H-24 with susceptible parents CT-1 and CT-2. The virus was transmitted by viruliferous whiteflies and virus infection was detected by sandwich ELISA. F2 generation showed moderate resistance with scores ranging from 1.58-3.21. Segregation of disease resistance was observed among the population. Virus detection of the F2 populations (scoring 1 or 2) showed virus titer which were not statistically different from H24 but were significantly different from CT-1, CT-2 and susceptible control. The disease severity and virus titer in infected plants of F2 populations showed positive...

Thermal energy use in three Swedish greenhouses – the outdoor temperature-dependent variation and the influence of wind speed under no-sunlight conditions CIGR Journal
Katarzyna Maslak; Swedish University of Agricultural Sciences, Dept. of Biosystems and Technology, Alnarp; Sven Nimmermark; Swedish University of Agricultural Sciences, Dept. of Biosystems and Technology, Alnarp.
Thermal energy is used in greenhouses for the temperature and humidity control.  In the North of Europe, energy expenditures have a significant share in the total greenhouse production cost.  A study was performed to quantify and analyze the use of thermal energy in three Swedish commercial greenhouses (two with tomatoes and one with ornamental plants), to test the hypothesis that substantial amounts of heat are used at higher outdoor temperatures, and to investigate the influence of the wind speed on the energy use under no-sunlight conditions.  Hourly climate data were registered by means of Priva control systems.  The use of thermal energy was computed based on the readings from the flowmeters and the temperature of the inlet/outlet water to/from the...

Development of chitosan-glucose and chitosan-citric complexes edible coating to improve tomatoes post-harvest quality CIGR Journal
A., El-Beltagy; Eissa, Ayman H. Amer; S., El-Sayed.
 The effect of different shrimp chitosan molecular weights as well as shrimp chitosan complexes (chitosan-glucose and chitosan-citric) on the quality characteristics of the stored (at 7°C±2°C and 90% RH) tomato fruits (Lycopersicum esculentum) was investigated.  Coating tomatoes with high molecular weight chitosan (H.M.C.G) significantly improved firmness and weight loss.  The lowest weight loss was found in high molecular weight chitosan-glucose (H.M.C.G) treatment followed by the fruits coated with high molecular weight chitosan (HMC) and then uncoated tomato fruits.  Both molecular weights was clear on retarding the total acidity loss especially for stored tomato fruit coated with low molecular weight chitosan, while control tomatoes exhibited a larger...

Development of passive evaporative cooling systems for tomatoes Part 1: construction material characterization CIGR Journal
Olorunnisola, Abel Olajide; Okanlawon, Sunday Adewale.
The management of large volumes of agroforestry residues constitutes one of the global environmental challenges today.  These residues tend to accumulate in the environment, resulting in water, air and land pollution.  In response to rising costs associated with waste disposal and increasing environmental demands, the sustainable conversion of wastes into useful products is becoming increasingly important.  In the same vein, the quality and shelf life of tomatoes are compromised within a few days if not properly stored and preserved.  Although, a number of researchers have worked extensively on the development of evaporative cooling systems in an effort to tackle this menace, finding durable construction materials remains a challenge.  The broad objective...

Effect of the consumption of tomato paste on plasma prostate-specific antigen levels in patients with benign prostate hyperplasia BJMBR
Edinger,M.S.; Koff,W.J..
The consumption of tomatoes and tomato products has been associated with a reduced risk of prostate cancer. We observed a decrease of 10.77% in prostate-specific antigen (PSA) levels in patients with benign prostate hyperplasia who were submitted to daily ingestion of tomato paste. This was an experimental rather than a controlled study with a sample of 43 men ranging in age from 45 to 75 years, all with histological diagnoses of benign prostate hyperplasia and plasma PSA levels of 4-10 ng/mL. All patients received 50 g of tomato paste once a day for 10 consecutive weeks and PSA levels were analyzed before, during and after the consumption of tomato paste. ANOVA for repeated measures was used to compare PSA levels before, during and after the consumption...

A method for the determination of two Alternaria toxins, alternariol and alternariol monomethyl ether, in tomato products BJM
Motta,Silvana da; Soares,Lucia M. Valente.
Tomatoes, as any soft skinned fruit, are easily susceptible to fungal rot. Alternaria is the genus most frequently encountered in tomatoes. A. alternata and other spp. have been shown to produce the toxins alternariol monomethyl ether (AME) and alternariol (AOH) in tomatoes. A method for determining AME and AOH in tomato products was developed and evaluated. The method involves extraction with methanol, clarification with ammonium sulfate, and partition to chloroform. Quantification was conducted by high performance liquid chromatography with diode array detector (DAD). Average recoveries were 98.7% and 84.1% for AME and AOH, respectively. The quantification limits of the method, defined as the minimum amount that allowed quantification and confirmation by...

Nucleotide diversity of a major carotenoid biosynthetic pathway gene in wild and cultivated Solanum (Section Lycopersicon) species Braz. J. Plant Physiol.
Araújo,Ana H.; Fonseca,Maria Esther de N.; Boiteux,Leonardo S..
A polymerase chain reaction (PCR)-based approach was employed to isolate putative alleles of the chromoplast-specific lycopene beta-cyclase (CYCB) gene from wild and cultivated tomatoes [Solanum (Section Lycopersicon)]. The objective of this work was to establish an effective PCR protocol by testing DNA samples from distinct germplasm accessions with a primer pair designed to selectively target conserved regions present in the available CYCB sequences. This PCR optimization allowed the amplification of 1219 out 1666 bp of the gene in six taxa: S. cheesmaniae, S. peruvianum, S. neorickii, S. pennellii, S. pimpinellifolium and S. lycopersicum. Sixty-three mutation sites (31 transitions, 18 transversions and 14 single base deletions/insertions) were detected...
